Fantastic video here. I'm 65, old mechanic and never knew the th400 could be so much Fun.!

Nice work. Thats way better than the spacer.

Thank you! Exactly what I noticed with that slide in adapter. I’m running the fancy TCI flat flex plate with the raised pads. Converter would not pull up to them. Bottoming out in the adapter. Turbo car, has all the trans and thrust mods, but still beating on the thrust!

Brilliant!

You should make and sell those spacers.

​@mountainsgarage You fo realize that the pilot on the PTC converter unscrewed off of the torque converter? Before you welded in the center there is 2 holes for a spanner wrench to unscrew. Wouldn't it be better to remove and weld off of the converter instead of welding to the converter? That way if you ever decide to put trans and converter on another engine you can just unscrew and machine down?

nice video thanks

Great video! Really enjoy all the th400 videos. I actually ran into this problem this last weekend. Wished I’d thought of this solution. I got rid of your favourite adapter spacer and added the factory one on the outside. Lol. Anyway, I have 0.200” between the flexplate and the torque converter pads. Close enough to 3/16” or should I shim it a bit with washers?

Thanks U!

Hell of a idea got to work better

At 1st this really didnt make sense to me. By the end I figured out, you are letting the flex plate hold the converter from the pads and not the snout bottoming out and making it solid.

I used a short crank 4l80e flex plate

Hi Shawn. I have a vega in which I plan to update with an LS since the engine needs to be redone and know nothing about LS so I am learning a lot through your videos. At first I thought you were describing a trans thrust washer versus the crank. Apparently this is an aside I will need to address also. Thank you for the info. Forgive my stupidity here, but as in Algebra in HS, I'm not following here. If the crank is attached to the flywheel and the flywheel is bolted to the converter, with or without your update, the crank should still get pressure, yes? So your mod is just to center the converter on the flywheel/crank, right? With or without your mod, and if the converter was spaced out a1/8th", the center of the converter won't touch the crank flange, right? I feel I'm missing something important here.

Have you ever drilled out oil holes in cam bearings for better circulation

Hey Shawn, if you decide to make any of these spacers please let me know. PayPal ready!

Does a 2000 lq4 6.0 need any mods to use a th400 ? It bolted right up no adapters Am i going to have problems i dont know about yet ??

i cant use a allison waffle clutch disc on direc, foward drum, for street and drag on my th400 transbrake?

Just machined out of Mild steel? Going to have a friend make one up for me.

Could you not lathe down the pilot adapter so that it does not bottom out on crank?

Hey Shawn love the videos. I’m building a th400 soon and could use your help. What’s the best way to contact you? I don’t have Facebook, thanks

How do I get in touch with you to purchase spacer?

So I'm going to have to buy a converter for my LH6 5.3 and th400 can I buy a converter thats made specifically for the ls and th400 or will I have to do this?

Hey Shawn, I love this, I have always thought those dam spacers were garbage.. Any chance you would be interested in cutting a few of these for me and letting me purchase them from you?

Howdy.....anyone find a place to buy these weld on spacers yet? Thanks!

How did it work out on your buddies truck?

Gotta keep that bench from rusting 😉🤣

Where you located think you can help me out with this ls to PowerGlide

👍👍

Can I order that extension?

Sent you a email .

Hi I really like your videos, great info on the th400 transmissions, I understand what you doing with this mod letting the flexplate flex as It should and unloading the crankshaft, but if you run some sort of billet aluminium "flexplate" ( like me on my 2j) or this mod don't solve the issue for your buddy, an other way is to mount a roler bearing on the crankshaft like these guys m.kzfaq.info/get/bejne/oseclLeIr5rRdKM.html about 4:30 in the video Don't know if you have seen this before or what you're opinion on this solution is? It's a lot more complicated for once...
